Abstract
La présente invention concerne un système conçu pour déterminer l'impédance de masse d'un système de conduite et comprenant une gaine conductrice et une résistance ayant une valeur connue. La gaine conductrice est conçue pour entourer une partie d'un conducteur logé dans un système de conduite. Un couplage capacitif se produit entre la gaine et le conducteur pour établir une source de tension. La résistance est électriquement couplée entre la source de tension et un composant métallique du système de conduite, et une chute de tension est lue sur la résistance pour déterminer la santé de l'impédance de masse du système de conduite.
